QGL Class Reference
[OpenGL module]

Detailed Description

Normally you can ignore this class. QGLWidget and the other OpenGL^* module classes inherit it, so when you make your own QGLWidget subclass you can use the identifiers in the QGL namespace without qualification.

However, you may occasionally find yourself in situations where you need to refer to these identifiers from outside the QGL namespace's scope, e.g. in static functions. In such cases, simply write e.g. QGL::DoubleBuffer instead of just DoubleBuffer.

^* OpenGL is a trademark of Silicon Graphics, Inc. in the United States and other countries.
